A Application filed July 11, 1917. Serial No. 179,898.

.county of Hennepin and State of Minnesota,'have invented a new and usefulVVin- (low-Frame and Slip-Sill for Drop-Sashes;-

and we do hereby declare the. following to be a full, clear, and exact description of the inventiom such as will enable others skilled in the art to which it appertains to make and use thesame. f I

This invention relates to an improved slip sill and window frame for lowerable or drop sashes, and one of the objects of the invention is to provide a windowframe of this 'kind having a pocket or box in its lower portion for the reception of the upper and lower'sashes, and in combination with a slip sill-for covering the opening to the pocket or' boxfthereby entirely concealing the sashes.

A further object of the invention is to provide an improved slip sill window and frame therefoiywhose.construction will provide, as near. as possible, a substantially weather-, 'waterand dust-proof sill, when the sashes are raised or dropped or lowered entirely into the pocket -or boxof the window. frame.

A further object of the invention is the provision of an'improved water tight slip window sill, when the sashes are raised or lowered.

A further object of the invention is to provide a device of'this kind in which the without in any way upper and lower sashes may be dropped or lowered into a pocket or box below the. sill, moving the storm sash or screens.

'Afurther object of the invention is the' provision of an improvedslip sill for windows, whose operation will permit the.

screensor storm sash to be placed adjacent the outside of the window frame and not be moved when the sill is operated.

A further object of the invention is the I provision of an improved window frame provided with a sectionalwindow sill, the sections of which being so hinged and capable of hinged movements, whereby the sections may be tilted so that the upper thewindow frame and its and lower sashes may be moved or lowered or dropped into a pocket below the sill.

A further object of the invention is the provision of means formed in the inner and outer guide rails of the window frame to permit the sectionsof the sill to'be swung open, whereby the upper and lower sashes mziy be lowered or dropped. a

n practical fields, the details of construe tion -may necessitate alterations falling within the scope of what is claimed.

- The invention comprises further features and combination'of parts,;as hereinafter set forth, shown in the drawings and claimed. In the drawings I Figure l'is a view in elevation of a portion of the side wall or the side of a house,

showing theimproved window frame with a pocket for the upper and lower sashes, as-

applied.

Fig. 7- isadetail view of one end of one of the sill sections, showing a weather strip for the end of the section.

Referring more especially to the drawings, 1 designates a window frame, which may be of any conventional construction,

with the exception that the same shall be .of' sufficient length, whereby its lower or'. 'tion substantlally for one-third of its length,

may be extended downwardly'between the inner wall 2 of the house ordwelling and the outer wall 3 thereof, thereby forming a pocket 4, for the reception of either one or' both. of the upper and lower sashes 5 and 6. The sides of the window frame are provided with the inner and outer stop'guide rails or strips? and 8, and the parting strip 9, which is dlsposed substantially intermediate the inner and outer strips 7 and 8, and

acts as the guiding means for the upper sash, that is, together with the parting strip,

, which is inserted, as at into the portion sill.

10 of the window frame; The lower part of each strip 8 is provided "with a recess 16. These recesses are oppositely disposed, and 'the sill of the window frame comprises the inner and outer stationary sill sections 17 and 18, and the intermediate hinged or movablesections 19 and 20. The outer edge portion' of the stationary section 17 is provided with a rabbet 21, and to the vertical wall of this rabbet one leaf ofeach hinge 22 is secured by 'the screws 23. The other leaf of each hinge 22 is secured to the inner edge of the movable sill section 19 by the screw 24, whereby, when the section 19 is lowered, as shown in Fig. 4, its inner portion will rest in the rabbet 21. The stop guide strip 7, at its lower portion is provided with a recess 25. The recesses 25 ofboth strips 7, only one of which is shown, are designed to be directly opposite to each other. The lower wall 26 of each recess25 is curved on an arc concentric with the hinge 22, whereby the extension 27 of each end of the sill section 19 may swing or move into the recess 25, when the sill section 19 is raised, as shown in dotted lines in Fig. 4, to permlt the lower sash'to be dropped or lowered into the pocket 4. The stationary sill section 18 is rovided with a rib or flange 28, over WhlCl'l the curved flange 29 of the sill section 20 extends, whereby the edge of the flange 29 may engage or rest ,on the upper face .of the sill section 18.

Owing to such over-extending of said flange 29 and the overlapping of the sill sections 19 and 20, water easily sheds oil the window of suitable screws 30, is one of the leaves of the hinge 31, while the other leaf is secured to the outer curved surface of the flange 29 of the sill section 20. The hinge extends up from the sill section 18, thereby supporting the sill section 20, spaced from vthe section 18, so that water can shed, and to permit cleaning under the section 20. The sill section 20, when opened may be positioned so that its end may enter the recess 16. The inner portion of each end of the sill section 20, in fact its corner, is cut away, as shown at 32 tomake room for the parting strip 9, when the sill section 20 is lowered, as shown It is to be noted that the Secured to the sill section 18 by means in full lines in Fig. 4. Where the inner portion of the sill section 20 is adjacent the partin strip 9, when said section 20 is low ered, t e artin strip has a notch '33, the lower en of w ich supports the sill "section 20. It is to be observed that the sill S ctions 19 and 20, when lowered, as shown in full lines, overlap eachother. The underface of the outer portion of the section 19 is provided with a longitudinal groove or recess 34, for the reception of the correspondingly shaped sheet metal plate 35. This sheet metal plate 35 is bent to provide the portion 36 which is engaged by the upper inner edge of the sillsection 20, and to provide the groove 37 ,for the reception of the plate 38, which is secured as at 39 to the sill section 20. This sheet metal plate 34 is provided to insure a tight connection between the two sill sections 19 and 20. Said plates 34 and 38 may be constructed of any suitable material other than metal; if need be, they may be constructed of a suitable material that will not only exclude dust, but also water. metal,'which is preferable, the connection between the two plates may be such as to exclude dust and the like. The side-walls of the window frame between the stop guide strips 7 and 8 and the parting strip are each provided with suitable grooves 40 'forthe reception of the weight bands "or; cords 41 Y of the weights 42 and said upper and lower sashes. The lower part\of each side of the an angular recess 43, into which a sheet metal spring angular weather strip 44 (one of which is secured to each end of the sill section 20) engages or springs, which not only acts as a weather strip and to close one of the grooves 40 to exclude dust and water, but also to substantially latch the sill section 20 in its lowered position, as shown in full lines in Fig. 4. By opening the sill sections 19 and 20, as shown in dotted lines in Fig. 4, said upper and lower sashes may be lowered or dropped within the pocket 4, after which said sill sections may be closed. The window frame and the various stationary and movable sill-sections may be constructed in any suitable proportion, and made from any suitable material, and the groove 28, and such other minor details may be varied or altered in their detail construction and proportion within the scope of the claims appended hereto. By means of this improved sectional sill, one or more of the sections being movable, and by virtue of said movable and pocketed upper and lower or window'screen 45 (wh ch is arranged 130 However, if constructed of within the window and resting on the stais claimed as new and useful is 1.
